发明名称 Liquid ejecting apparatus and ejection inspecting method
摘要 A liquid ejecting apparatus includes: a head which ejects a liquid from nozzles; a first electrode which charges the liquid with a first potential; a second electrode which is charged with a second potential different from the first potential; and an inspector which inspects whether the liquid is ejected from the nozzles based on a variation in a potential caused in at least one of the first and second electrodes by ejecting the liquid charged with the first potential from the nozzles to the second electrode and which determines whether the inspection of liquid ejection from the nozzles is normally executed based on the variation in the potential during a non-ejection period in which the liquid is not ejected from all of the nozzles.
